COLLAPSIBLE YARN DYE TUBE CROSS REFERENCE TO RELATED APPLICATION Thisapplication is a continuation-in-part of copending application, Ser. No.l58,729, filed July 1, 1971 and entitled Collapsible Yarn Dye Tube.

BACKGROUND OF THE INVENTION Perforated dye tubes, per se have been usedfor many years to improve the uniformity of package yarn dyeing. Suchdye tubes are generally unitary in structure and manufactured ofstainless steel. A yarn package is produced around the dye tube wherebyupon the introduction of a dye liquor internally thereof, the dye liquorpasses through the perforations onto the yarn at the inside of thepackage as well as from the outside of the yarn package. Further,perforated dye tubes have been constructed from telescoping sections,both of which are perforated to permit the admission of dye liquor fromthe inside as well as the outside of the yarn package.

In recent years, further means for dyeing have been developed such asdye springs which, though not tubular, receive a sleeve or the liketherearound with the yarn package produced around the surface of thesleeve. The sleeve which may be a knit tube, burlap, paper or the like,facilitates ease of winding and proper package formation. Thereafter,the dye spring may be longitudinally compressed upon the application ofpressure so as to reduce the overall length of the yarn package and thuspermit a larger number of packages to be dyed in a single dye kettle.Still further, while the majority of the perforated dye tubes andsprings in the past have been constructed from stainless steel so as topermit continued use thereof, plastic perforated dye tubes and springshave made their appearance in the marketplace,

A further improved collapsible dye tube is described and claimed in mycopending application, Ser. No. 158,729, filed July 1, 1971. The presentinvention represents still a further improvement over the previouslymentioned dye tubes including that described in my copendingapplication. As such, the present invention further improves the dyetube art by providing a collapsible tube that is capable of selfalignment on the dye spindle, a better driving relationship between thedye tube and the winder drum, ease of assembly to insure properalignment between the perforations in the side wall of the dye tube, anda construction which permits use of the dye tubes without the normallyused spacers. The dye tube of the present invention thus furtherincreases the dyeing capacity of the dye kettle, eliminates the need forstainless steel spacers which reduces the operating costs of the dyeingprocess.

Since a better driving relationship is established between the dye tubeand the winder drum a more uniform package of yarn is produced which, ofcourse, improves the dye uniformity. Probably the most importantimprovement afforded by the collapsible dye tube of the presentinvention is the fact that, whereas the normal use of a dye tube in adye kettle calls for the use of a spacer between dye tubes, theoperators in many instances omit the use of the spacers. As such, aloose fit has existed with prior tubes on the dye spindle. ftentimes theloosely fitting packages are out of alignment with one another whereby,upon receipt of pressure in the kettle, the dye tubes are improperlycollapsed thus damaging the yarn wound thereon. More'- over, with animproper collapse of the dye tubes, complete collapse will not occur andthe full increased capacity of the dye kettle will not be realized. Thepresent invention thus provides a collapsible dye tube that overcomesknown disadvantages of the prior art while further improving economicsand quality of the dyeing operation.

The prior art, as mentioned above, contains various teachings ofperforated dye tubes, dye springs and the like. There is, however, noteaching or suggestion in the prior art of the collapsible, disposableyarn dye tube as taught by the present invention and described andclaimed herein. Exemplary of the prior art are U. S. Pat. Nos. 974,127to Daniel] et al; 1,500,046 to Bell; and 3,563,491 to Hahm et al.

SUMMARY OF THE INVENTION It is an object of the present invention toprovide a novel collapsible perforated dye tube.

A further object of the present invention is to provide an improvedcollapsible dye tube having dye spindle alignment means.

A further object of the present invention is to provide a novel dye tubeassembly having alignment means thereon to prevent closure ofperforations therein.

Still further, another object of the present invention is to provide animproved collapsible dye tube which avoids the necessity of spacersbetween adjacent dye tubes in the dye kettle.

Yet another object of the present invention is to provide an improvedcollapsible dye tube whose econom ics permit disposal after a singleuse.

Generally speaking, the present invention is directed to a collapsibledye tube assembly comprising a first tubularmember, saidfirst memberhaving an outer end and an inner end and defining a plurality ofopenings along at least a major portion of the length thereof, and asecond tubular member, said second tubular member having an outer endand an inner end and defining a plurality of openings along at least amajor portion of the length thereof, said second tubular membertelescoping for a limited distance at its inner end in the inner end ofthe first tubular member, said first and second tubular members havingdye spindle alignment means received on the inner peripheries thereof,and said outer ends of said first and second tubular members beingadapted to make even contact with an adjacent dye tube assembly and toevenly transmit pressure therefrom.

More specifically, the tubular members comprising the instant dye tubeassembly each have an outer end and an inner end, the inner ends ofwhich mate in tele- 'escopes for a limited distance into the inner endof the other member. Thereafter, once yarn has been wrapped around thedye tube assembly, pressure at the ends thereof will cause furthertelescoping of the members to a collapsed condition whereby a largernumber of dye tubes may be placed at one time in a dye kettle.

Each member further has a plurality of openings or perforationstherearound along at least a major portion of the length thereof so asto permit dye liquor to pass from the inside of the dye tube through theyarn package. As such, care should be taken during collapse of thefinished package in the dye kettle to prevent closure of the openingsdue to misalignment between the members. Such a happening can beprecluded by the use of alignment means on the members whereby duringassembly, the openings can be properly aligned so that after collapse,sufficient openings remain in the tube to permit the passage of adequatedye liquor therethrough.

The tubular members comprising the dye tube assembly of the presentinvention are also provided with dye spindle alignment means so as tosubstantially center the yarn package around a dye spindle. Such spindlealignment means may comprise a protrusion secured to the inner peripheryof the tubular member and extending inwardly therefrom. The protrusionmay be solid to form a flange, may be made up of a plurality of separateprojections disposed in the circular pattern, or the like. The dye tubehas yarn wound therearound on a winding machine while being held thereonby a mandrel extending into each end of the tube. The spindle alignmentmeans must therefore be provided within the tubular members a sufficientdistance from the other ends thereof to avoid interference with themandrel. Further, additional spindle alignment means may be providedalong the lengths of the tubular members so long as the additional meansdo not interfere with collapse of the dye tube.

In winding yarn onto the dye tube, a driven drum is brought into drivingengagement with the dye tube so as to rotate same at a particular speedwhen receiving yarn therearound. Once the yarn starts onto the package,however, the driven drum then engages the yarn. The dye tube assembly ofthe present invention is thus preferably provided with outer dimensionssuch that driving engagement is realized between the assembly and thedriven drum at the middle of the assembly as well as the opposite outerends thereof. As such, a more uniform yarn package is produced and lessstresses are produced in the tube during winding.

The opposite outer ends of the dye tube assembly under previous practicewere adapted to receive a spacer or collar that separated one dye tubefrom an adjacent dye tube. In many operations, these collars became lostor became burdensome to the operators during use. As such, their use hasbeen omitted in many instances to the general detriment. of theoperation. Omission of the collars has permitted individual dye tubes toshift out of proper contact with an adjacent tube since the internaldiameter of the tubes has been larger than the diameter of the dyespindle. Hence, when stacking one yarn package on the other, the tubeends would not matter. Thereafter, once pressure was applied to collapsethe tubes, a uniform amount of pressure was not experienced by themisaligned tubes, whereby the tubes collapsed nonuniformly. Waste yarnwas thus produced on the improperly collapsed tubes and dye capacity waslost due to incomplete collapse of the tubes. This problem has now beensolved by the addition of the dye spindle alignment means in conjunctionwith the thickened outer tube ends. Use of the present dye tube thuseliminates the need for collars between the yarn packages by design tofurther improve dyeing costs and efficiency.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A dye tube assembly accordingto the teachings of the present invention is shown in partial crosssection in FIG. 1 in a winding environment. The dye tube assembly isgenerally indicated as 10. Mandrels 50 and 60 are associated with awinding machine and are shown in phantom extending into opposite ends ofthe dye tube assembly 10 so as to support same for winding a yarntherearound. A drum is further shown in phantom to be in contact withdye tube 10. Drum 70 is driven by means not shown to rotate tube 10 andthus wind yarn thereon at a particular speed.

Dye tube 10, which is shown in cross section from line I-I down,comprises a pair of tubular members 20 and 30. Tubular members 20 and 30have outer ends 22 and 32 and inner ends 24 and 34 respectively and havea plurality of perforations 25 and 35 along at least a major portion oftheir lengths. The inner end 34 of tubular member 30 is showntelescoping into inner end 24 of tubular member 20, the initial amountof telescoping being limited by a plurality of stops 33 positionedaround the periphery of tubular member 30 and extending outwardlytherefrom. Stops 33 should be of sufficient rigidity to limit initialtelescoping while of sufficient resilience to permit further telescopingunder sufficient pressure.

Tubular members 20 and 30 are also shown to have internal dye spindlealignment means, illustrated as protrusions 27 and 37 respectively attheir outer ends 22 and 32. Protrusions 27 and 37 are positionedinwardly along their tubular members to avoid interference with mandrels50 and 60. Dye spindle alignment means are provided to insure properplacement of the dye tube with yarn wound thereon over the dye spindle.While protrusions 27 and 37 are shown to be a continuous flange in FIG.1, a plurality of spaced apart projections 127 are illustrated in FIG.2. Thus the particular design of the dye spindle alignment means is notcrucial so long as the yarn package can be easily placed over the dyespindle, no interference is caused during winding or tube collapse anduniform alignment is caused between yarn packages. Regarding collapse oftube 10, member 30 is illustrated as having a further internalprotrusion 37' at its inner end 34. Protrusion 37' is preferably alsoincluded since its presence will not interfere with tube collapse andsince it provides a further guide for the dye spindle. Moreover, the dyespindle alignment means, regardless of the type are preferably beveledor tapered on the sides thereof as at 28, 38 and 38. Such beveled ortapered edges will guide a dye spindle back to the central openingdefined by the alignment means and assist in placement of the packageover the dye spindle.

Outer ends 22 and 32 of tubular members 20 and 30 also have greater wallthickness than the remaining length of the members. Thus when one tubeis abutted by another tube 10 and collapsing pressure is applied, goodcontact is maintained by both tubes 10 and pressure is evenlytransmitted through the tubes for a smooth and proper collapse thereof.Without a spacer or collar between adjacent dye tubes and without thestrengthened outer ends of the tubes, there is the danger, as mentionedabove, that the tubes will collapse improperly and jam, thus reducingdyeing capacity and producing bad quality yarn.

Outer end 32 of member 30 is further shown to have substantially thesame outside diameter as tubular member 20. Outer end 32 of member 30thus makes equal contact with the winder drum 70 as does tubular memberthus establishing a driven relationship on both ends of the dye tube 10to improve the winding operation.

FIG. 2 shows a tube 110 positioned around a dye spindle S (in phantom).A plurality of projections 127 are secured to tubular member 120 andextend inwardly therefrom. The position of tube 110 with respect to dyespindle S is thus governed by the dimensions of projections 127.

As shown in FIGS. 3 and 4, tubular members 220 and 230 may be providedwith mating guide means 221 and 231 respectively. Guide means 221 areillustrated as serrations around the inner periphery of the inner end222 of tubular member 220 while means 231 are serrations around theouter periphery of inner end 232 of tubular member 230.

' As shown in FIG. 4, serrations 221 and 231 mate during initialtelescoping and accomplish a dual purpose.

First rotational movement of one of the tubular members with respect tothe other is precluded. Secondly, the perforations 225 and 235 areprealigned to permit complete collapse of the dye tube withoutappreciable blockage of the perforations. Guide means 221 and 231 thuscooperate to cause tube 210 to rotate as a unitary structure duringwinding and guarantee proper dye distribution during dyeing. Normallyguide means positioned only at the respective inner ends of the tubularmembers accomplish the intended purpose. If, however, guide means areneeded along a further length of the tubular members they may be soprovided, taking into consideration that the dimensions thereof must notinterfere with collapse of the tube.

While guide means 221 and 231 are illustrated as serrations, certainlyother designs are suitable such as a key and slot arrangement, matingnon circular periphcries in general and the like.

Referring to FIGS. 1, 5 and 6, a plurality of yarn packages Y arepositioned around a dye spindle S. Spindle alignment means 27, 37 and37' have placed the spindle S at substantially the center of the dyetubes. Further, the outer ends 22 and 32 of the individual dye tubes areof substantially the same outside dimension to provide a good abuttingrelationship between adjacent dye tubes. Moreover, as mentioned earlier,the outer ends 22 and 32 have greater wall thickness and thus presentrigid members on opposite sides of the abutments. Once pressure isapplied axially along the tubes, the above mentioned features permitcorrect collapse of all of the tubes as shown in FIG. 6. Hence theanticipated additional yarn packages may be placed in the dye kettle andall dyed uniformly.

Making reference to FIGS. 1, 5 and 6, it can be seen that the dyepackages Y produces from the collapsible dye tubes according to thepresent invention may be successfully employed without the use ofspacers between adjacent dye tubes. Outer ends 22 and 32 of tubularmembers 20 and 30 respectively have thicker walls than the remainder ofthe tubes with substantially the same outside dimensions. The outer endsof adjacent dye tubes thus properly abut each other and when pressure isapplied thereon, uniformly transmit pressure from tube to tube toproperly collapse same.

The dye tubes of the present invention, for best operating results,should be constructed of a material that will distort upon receivingsufficient pressure to permit complete telescoping of the dye tube tothe point where the inner end 24 of tubular member 20 abuts a shoulder32' formed by the thickened outer end 32 of tubular member 30.Furthermore, the temperatures during dyeing and drying generally rise toapproximately 300 F., and an important feature of the present inventionis to provide a dye tube of a material whose softening point is higherthan 300 F. Hence, during the dyeing and drying cycle, the dye tube willmaintain its integrity and will not distort, shrink or otherwiseexperience dimensional change such that the yarn package tightens aroundthe spindle S and thwarts easy removal therefrom.

Once the dye tube of the present invention has been used, the economicsof manufacturing same are such that the tube may be discarded. Thepreferred method of manufacture of the tubular members 20 and 30 thatcomprise dye tube assembly 10 is injection molding of a plastic havingthe strength characteristics and physical characteristics such thatproper longitudinal collapsing of the assembly is permitted while theassembly will not shrink or distort at temperatures around 300 F.Polypropylene has been found to be quite suitable for the manufacture ofthe dye tube assembly according to the present invention and ispreferred.

Openings or perforations 25 and 35 of the tubular members 20 and 30respectively that permit passage of dye liquor therethrough to theinside of the yarn package, are shown in the figures as rectangular inshape. Certainly openings of any geometric configuration may be suitablyemployed provided that the size and number of openings is sufficient topermit a proper amount of dye liquor to pass.

Having described the present invention in detail, it is obvious that oneskilled in the art will be able to make variations and modificationsthereto without departing from the scope of the invention.
